The best in the world have one thing in common: they are experts at failure.
Roger Federer just won Wimbledon at the British Tennis Open. No one that knows tennis ever thought that Federer could regain his masterful tennis game and yet today, he won and regained the #1 player status in tennis.
Michael Jordon, Tiger Woods, Newton Fahl, Francisco Banchs and I are or were trying to be among the best in the world and yet we have all failed over and over.
What makes us different is that 99% of people will never TRY to be among the best in the world and therefore, they are NOT experts at failure.
Another difference is that those of us who want to be among the best NEVER STOP TRYING. Education, Passion and Persistence are truly the characteristics that separate those that succeed at a very high level and those that remain mediocre.
Do you really want to have your dentistry performed by someone who will never try to be excellent?
Only you can answer that question.
